Subject [jira] [Commented] (CASSANDRA-5943) Add sstablesplit dtest
Date Thu, 29 Aug 2013 19:20:52 GMT

Daniel Meyer commented on CASSANDRA-5943:
-----------------------------------------

Here is my initial stab at a test plan.  I will go ahead and begin working on implementing
this; however, feedback is appreciated.

1) Run cassandra-stress to load some set amount of data into a single node cluster.
2) Force a compaction. Amount of data will be tuned to produce an sstable of size N mb.
3) Run sstablesplit on resulting large sstable of size N from 2).  sstablesplit will be run
with a size parameter to be some fraction of N.
4) Verify that sstable has been effectively split into new sstables with correct size.
5) Run cassandra-stress to ensure data can be read back without errors.


The amount of data and resulting size parameter passed to sstablesplit will be tuned to ensure
dtest is effective but also reasonably fast.
